An image stabilization apparatus comprising: an image stabilization unit that performs image stabilization by changing a crop position at which part of image is cropped from an image obtained by photoelectric conversion of an optical image formed through a detachable lens unit by an image sensor based on a vibration amount detected by a vibration detection unit; a control unit that controls the image stabilization unit so as to shift the crop position by a predetermined swing back amount toward a center of the image; and a determination unit that determines whether or not zooming is performed based on focal lengths obtained from the lens unit at a predetermined time interval, wherein the control unit increases the swing back amount in a case where zooming is performed than in a case where zooming is not performed.
Legal claims defining the scope of protection, as filed with the USPTO.
2. The image stabilization apparatus according to claim 1 , wherein, in a case where zooming is performed, the control unit multiplies the change amount in a case where zooming is not performed by a predetermined coefficient k (k>1).
3. The image stabilization apparatus according to claim 1 , wherein, in a case where zooming is performed, if the change amount of the focal length is a first change amount, the control unit obtains the change amount of the angle θ in a case where zooming is performed by multiplying the angle θ in a case where zooming is not performed by a larger coefficient k (k>1) than in a case where the change amount of the focal length is a second change amount which is smaller than the first change amount.
4. The image stabilization apparatus according to claim 1 , wherein, in a case where zooming is performed, if a time interval for obtaining the focal length is a first time interval, the control unit obtains the change amount of the angle θ in a case where zooming is performed by multiplying the angle θ in a case where zooming is not performed by a larger coefficient k (k>1) than in a case where the time interval for obtaining the focal length is a second time interval which is shorter than the first time interval.
